Korea Flux Network (KoFlux)

KoFLUX is a network of micrometeorological tower sites that use eddy covariance methods to measure the exchanges of carbon dioxide (CO2), water vapor, and energy between terrestrial ecosystem and atmosphere. At present, over 6 tower sites are operating on a long-term and con tinuous basis. Researchers also collect data on site vegetation, soil, hydrologic, and meteorological characteristics at the tower sites.

KoFLUX's goals are to understand the mechanisms controlling the exchanges of CO2, water vapor and energy across a spectrum of time and space scales as one of the membership studies in Asia Flux and FLUXNET. KoFlux also provides ground information for validating estimates of net primary productivity, evaporation, and energy absorption that are being generated by sensors on the NASA TERRA RRA satellite.

KoFlux also has a goal to provide information to FLUXNET investigators and the public. KoFlux data will be available at the ORNL DAAC include monthly and annual heat, waper vapor, and CO2 flux, gap- filled flux products, ecological site data, and remote sensing products.

KoFlux research sites include:

Kwangneung Coniferous Forest , Kwangnung Research Forest, Pochun-gun, Gunggi-do, Korea
Kwangneung Deciduous Forest , Kwangnung Research Forest, Pochun-gun, Gunggi-do, Korea
Hari Rural Rice Paddy, Hari in Sukmo island, Gangwha-gun, Inchon, Korea
Suwon Suburban Rice Paddy, Experimental farm of Seoul National University, Suwon, Korea
Mixed Forests, Tak, Thailand
Farmland, Si Samrong, Thailand

Other sites are under development.

KoFLUX是一套微气象塔站网络，采用涡度协方差法（eddy covariance methods）测量陆地生态系统与大气间的二氧化碳（CO₂）、水汽及能量交换通量。目前已有超过6座塔站实现长期连续运行。研究人员同时会采集各塔站周边的植被、土壤、水文与气象特征数据。

作为亚洲通量网（Asia Flux）与全球通量网（FLUXNET）的成员研究项目之一，KoFLUX的核心目标是解析调控不同时空尺度下CO₂、水汽与能量交换过程的机制。此外，KoFLUX还可为验证美国国家航空航天局（National Aeronautics and Space Administration, NASA）TERRA卫星搭载传感器反演的净初级生产力、蒸发量及能量吸收量估算结果提供地面实测数据支撑。

KoFLUX的另一目标是为FLUXNET研究人员及社会公众开放数据共享服务。相关数据将由橡树岭国家实验室分布式主动存档中心（Oak Ridge National Laboratory Distributed Active Archive Center, ORNL DAAC）发布，涵盖月度及年度的热量、水汽与CO₂通量数据、间隙填充后的通量产品、生态站点特征数据以及遥感反演产品。

KoFLUX现有研究站点包括：

2. 韩国京畿道坡州市广陵研究林内的广陵落叶林站
3. 韩国仁川市江华郡Sukmo岛的Hari乡村稻田站
4. 韩国水原市首尔国立大学实验农场内的水原近郊稻田站
5. 泰国塔克地区的混交林站
6. 泰国Si Samrong地区的农田站

另有多个站点尚在建设中。
